Submitted a warranty claim, got this lovely response:
"
aFe recently entered into a civil judicial settlement with EPA to resolve disputes regarding its manufacturing, sale and installation of Subject Products. Although aFe has not admitted liability for violating the Clean Air Act, as part of the settlement it has agreed that, among other things, it will no longer (1) manufacture, sell, or install the Subject Products or (2) provide technical support (e.g., telephone support, online/chat support, warranty support) for the Subject Products. aFe has also agreed to provide you with this notice.
You have one of the "Subject Products"
This is from the US Government....sorry that I cannot be of further service to you on this matter.....
